AbstractPurpose -The purpose of this paper is to establish what is known regarding how supply network governance leads to network outcomes, what mechanisms underlie this relationship, and how context impacts it. Design/methodology/approach -A systematic literature review identified 44 conceptual and empirical studies. Purely dyadic studies were excluded. Synthesis used the context-intervention-mechanism-outcomes (CIMO) logic. Findings -From a categorization of contexts, governance instruments, mechanisms and outcomes a contingent conceptual framework is developed in the paper relating governance instruments to network outcomes dependent on the context. In general, formal instruments are adopted in dynamic and unstable circumstances defined as risky, uncertain, unpredictable or during organizational change. These instruments can result in coordination, control, viability and performance outcomes. Informal instruments tend to be adopted in contexts where prior relationships exist between actors. Research limitations/implications -Arising from the conceptual framework three robust propositions are developed. A more nuanced view of power and trust is proposed to augment the explanations provided by transaction costs and social embeddedness. This provides opportunities for further research, including longitudinal and comparative studies. Practical implications -The conceptual framework provides three propositions suggesting that in dynamic or unstable circumstances formal governance instruments can provide viability, control, coordination or performance outcomes. Informal governance instruments are more effectively used in established relationships to improve performance, control and viability. Originality/value -The synthesis reveals contingencies in the appropriate governance modes of supply networks for desired outcomes in specific contexts, resolving apparent inconsistencies between prior studies.

PurposeWithin the context of a sustainable supply chain, the purpose of this paper is to report on empirical longitudinal research on supply chain network evolution and dynamics of governance in a multi‐stakeholder supply chain sustainability initiative led by Nespresso, the speciality coffee division of Nestlé.Design/methodology/approachThe paper proposes a framework to study the creation and evolution of governance mechanisms over a five‐year period. Data from 48 semi‐structured interviews and 15 recent and historic documents were also analysed. The interviews were conducted among current and past representatives of all the organisations concerned including coffee traders, NGOs and farmers.FindingsIn contrast with literature on the subject, governance mechanisms initially relied mostly on informal mechanisms. Formal governance mechanisms were incorporated into the relationships to enable the supply chain network to grow and to provide clarity to all actors. Relational quality processes that increased trust were critical elements in the early phase, and were explicitly built into a second phase of development.Research limitations/implicationsBeing a single case study, some caution needs to be applied to generalise findings beyond the specific context studied. An additional methodological limitation is the limited number of actors involved in the overall supply chain network.Practical implicationsThe paper shows the importance of treating governance mechanisms within the supply chain not as a fixed variable to be determined once and for all in the beginning of a relationship, but rather to adapt the coordination mechanisms of the relationships.Originality/valueThe evolution of relationships over time has been “often called for but rarely chosen”. The case highlights the potential benefits of this type of research to develop an understanding of the evolution of relationships in a supply chain network.

Safety leadership is asserted to positively influence safety compliance amongst employees. We examine this assertion by conducting a systematic literature review of the available academic literature on safety leadership practices and observed safety outcomes. We identified 25 empirical studies, the majority of which measured leadership through generic scales (MLQ and LMX). Closer scrutiny of the outcome measures suggested that these were mainly aligned to the implementation and operations phases of the OHSAS 18001 safety management systems framework. We conclude that safety compliance has been narrowly defined in academic study, but in practice embraces a much wider range of activities. While safety leadership may contribute to successfully achieving these other actions, there is no empirical evidence for this. Moreover, there is considerable critique of transformational and transactional leadership, so that the specification of desired leadership practices is problematic. We propose that a broader conceptualization of safety compliance requires safety leadership to embrace 'plural' forms of leadership. We draw attention to the narrow range of contexts in which safety leadership has been empirically studied and suggests other settings for investigation.Alternative methods for investigating safety leadership other than scales of leadership behaviour are suggested to enrich our understanding of safety leadership and so improve safety compliance.
